The Filter Trojan Horse
Every person who signed up for Instagram on day one thought it was a filter app. That's it. Kevin Systrom knew this. He used it.
The filters were the best in the market. They drew people in. But the real product was the social network hiding behind them. People came for the filters. They stayed for the sharing.
"Every person that signed up for Instagram on that first day thought it was a filter app and that's it. But what we did was bootstrap the social network."
Number one advice: solve a problem. So many people found a company just to found a company.
Share Everywhere at Once
The second insight was distribution. People already had audiences on Facebook, Twitter, and other platforms. Instagram let you share to all of them simultaneously.
This meant your Instagram photo reached every network at once. It wasn't just an app — it was a megaphone plugged into every platform that already existed.
The Speed Illusion
Every photo app before Instagram took forever to upload. Systrom's team did one simple thing: while you were choosing a filter and writing a caption, the photo was already uploading in the background.
You hit Done. It posted instantly. Users were shocked at the speed. There was no speed. Systrom just hid the wait behind work you were already doing.
"Everyone was like — how did you make that upload so fast? We just hid all the work in the background."
